[PATCH 00/12] Add the ABI documentation to the admin guide

[Mauro Carvalho Chehab <mchehab+samsung@kernel.org>]

Hi Greg/Jon,

That's the rebased patches with add the ABI documentation to the
admin-guide. It is rebased on the top of driver-core/driver-core-next,
and it can work both on the "old" mode, where the scripts will
avoid codes that would cause troubles for ReST, or at the new mode,
with parses the description to the ReST output untouched.

Patches 1 to 3 improves the get_abi.pl for it to parse ReST format,
and to report where the errors/warnings occur at the ABI file.

Patch 4 is implements support for a Sphinx log facility (info). 

Patches 5 to 10 adds the new kernel ABI extension, making it ready
to parse files in ether "normal" or "rst-source" mode.

Patch 11 addresses a Sphinx issue, with is there since old vesions,
but it gets worse on Sphins 2.0: basically, the ReST parser is lazy:
if it receives too much stuff, it silently ignores the end of the content.
So, the extension needs to split the content on small chunks.

IMO, it is safe to apply patches 1 to 11 via Greg's tree. The only
potential conflict would be at patch 4, but looking at docs-next,
I don't see any changes at Documentation/scripts/kernelog.py.

Patch 12 actually enables everything. 

If Patch 12 gets merged via Greg's tree, it may rise a single-line
trivial conflict with docs-next, as it will be adding kernel_abi to the 
list of extensions at Documentation/conf.py, and Jon is likely
adding another extension. too.

So, it could be wise postpone patch 12 to be merged after both 
trees got merged upstream.

Patch 12 adds ABI with ReST-scaping code. I'll submit soon a
second version for the RFC patches with turns it to "clean" mode.

The entire ABI series (plus Documentation/features) is at:

	https://git.linuxtv.org/mchehab/experimental.git/log/?h=abi_patches_v4.2

And the ReST output (with Sphinx 2.0 - with IMO provides a nicer
output) is at:
